Hi brep how do you assemble the orphan meshes of two concentric cylinders? Why cant I use the assembly-constrain-coaxial to put the concentric cylinder's orphan meshes? Thanks

HI All, Is it possible to use the Assembly-Constrain-Coaxial constrain with orphan meshes of concentri cylinders? Also, If i try to replace the part from assembly with its orphan mesh, the parts will be separated out. HOw can we assemble two concentric cylinder's orphan mesh? Also, is it...

hi xerf, with the interface material of 0.01 thickness... the initial increment time is 0.01 and also i put increment size as 1e-20. Also the load is time - load 0-0 0.5-5 1-10.25 but still i get the same error "too....increment" the global seeding size is 2. I also changed the meshing...

Hi Brep I was doing the same "orphan mesh" techniqu to generate the layers of cohesive elements. instead of shell elements SC8R elements i am using the cohesive elements coh3d8...it seems my mesh orientation is ok. but still i dont know what should i do.......not able to run the problem...

Yes, I have defined the failure criterion but still not able to see the deleted elements. STATUS shows BLUE colour elements without deletion......

for my case, it says "too many attempts made for this increment"......i just used three parts....one cylider is 1.5 mm diamter and 0.01 mm interface layer and 1 mm outer tapered cylinder. *Material, name=Post *Elastic 116000., 0.33 *Material, name=cohesive *Elastic, type=traction...

Thank you very much for the suggestion. I will try according to this and let you know. By the way, you did it in Standard (Implicit) or in Explicit? Thank you!!

IN the abaqus manual, it is said that you can introduce the cohesive elements either in orpahn mesh (for already exisiting parts) and for model the part. So, i have used the already exisiting part to create the orphan mesh. Please help me in this regard!!!!

Since my geometry is very complicated, I used free meshing with tetrahedral meshes. I am using ORPHAN mesh (created from the already existing parts). COH3D8 is the element type I am uing on the cohesive zone.

The model is 3D. It is a dental post consisting of crown, core, post, cement and dentin. I want to see the debonding behaviour at the interfaces of post-cement-dentin. The materials are linear elastic, I am using Implicit (abaqus standard) method. Due to the complicated geomtetries, I am using...

HI, I read ABAQUS/CAE user's manual (v.6.5) 21.1 Modeling adhesive joints and bonded interfaces. It works for the plain surface geometries (like sandwich type structures) but I want to use it for the concentric cylindrical type parts. In fact, I want to model the debonding behaviour of dental...

Thanks...But I think there is a built in elements called "Cohesive elements" in abaqus 6.5 version. But, when I tried to use it I could not able to run the simulation. Also, which version of the Abaqus manual, you are suggesting?? ABAQUS Analysis User's Manual ->7.9.3 Crack propagation analysis...

Could any one please guide me how can I simulate the debonding behaviour (traction sepration elements) of the two cylinder type models in ABAQUS. It will be a life saving help from you. Thank you!!!! Regards

input file - element deletion Hi All, I am trying to do the element deletion simulation. There are five different parts joined with TIE constraints. I used such a command for each material. Even the generated stress is higher than the material strength, I cannot see the deleted elements during...

Hi All, I am using element deletion method to find out the failure of the materials. I use STATUS option from the DISPLAY GROUP to visualize the element deletion but I could not see any deletion. I have five parts in a model and they are in contact with TIE constrain. So, in this regard...
